The trailer of “Avengers: Endgame” revealed that the heroes have a plan to take on Thanos (Josh Brolin). The fact that some of the “dead” characters will be featured in the film makes it clear that they will find a way to change what the Mad Titan has done. One theory about how they are going to achieve that suggested that they will be using time travel.

Captain America (Chris Evans) returned only to fight against Thanos. Although the Avengers failed in their attempt, the fight will continue in the next film. According to a theory posted on Screen Rant, Cap will end up taking over the leadership role, now that Tony Stark (Robert Downey Jr.) is stranded in space.

The first thing the heroes will have to do is build a team. With new superheroes as the Avengers, Captain America will come up with a plan to undo what Thanos has done. One way to do this is through time travel.

One evidence that confirms that there will be time travel in “Avengers: Endgame” is the picture that showed the cast and crew recreating the Battle of New York scene from the first “Avengers” film.

The white suits of the Avengers team suggested that they will be going into the Quantum Realm. Ant-Man (Paul Rudd) has returned from the Quantum Realm, and the heroes may get the idea to use it to travel back in time somehow.

Another way the team can travel back in time is though the powers of Captain Marvel (Brie Larson). According to Screen Rant, Samuel L. Jackson has confirmed in a recent interview that the most powerful character in the Marvel Cinematic Universe also has the ability to time travel.

More details about what Larson’s character can do will be revealed in the upcoming film “Captain Marvel,” which is set two decades before the events in “Avengers: Endgame.”

“Avengers: Endgame” is one of the most highly anticipated films this year. The movie will be released on April 26, and the producers have already started the countdown to the premiere on Instagram.
